尝试从 Scala 应用程序通过Phantom插入 Cassandra 时收到以下错误代码。
Cassandra 版本与:dsc-cassandra-3.0.1 捆绑在一起
[错误] (run-main-0) com.datastax.driver.core.exceptions.NoHostAvailableException: 所有主机尝试查询失败(尝试:localhost/127.0.0.1:9042 (com.datastax.driver.core. exceptions.InvalidQueryException: 未配置的表 schema_keyspaces), localhost/0:0:0:0:0:0:0:1:9042 (com.datastax.driver.core.TransportException: [localhost/0:0:0:0: 0:0:0:1:9042]无法连接))com.datastax.driver.core.exceptions.NoHostAvailableException:尝试查询的所有主机都失败(尝试:localhost / 127.0.0.1:9042(com.datastax。 driver.core.exceptions.InvalidQueryException: 未配置的表 schema_keyspaces), localhost/0:0:0:0:0:0:0:1:9042 (com.datastax.driver.core.TransportException: [localhost/0:0: 0:0:0:0:0:1:9042]无法连接))
我已经阅读了 StackOverflow 中的其他此类问题,但没有找到解决我的问题的方法。
此外,我没有注意到任何其他错误日志中存在以下内容:
我的阅读是否正确localhost/127.0.0.1:9042
这不是归结为127.0.0.1/127.0.0.1:9402
- 这可以解释为什么它找不到正确的端口开口。
现在沿着这条路走下去,试图弄清楚这是否是一回事。
确保 Cassandra 正在运行。
我还跑了 sudo lsof -i -P | grep -i "listen" 带有以下输出(只是拉出 java 的):
java 4053 dan_mi_sun 85u IPv4 0xdbcce7039c377b9d 0t0 TCP localhost:7199 (LISTEN)
java 4053 dan_mi_sun 86u IPv4 0xdbcce703986952cd 0t0 TCP localhost:53680 (LISTEN)

关于这个问题可能是什么的任何想法?
找到了这个,但不确定它是否相关:
